Two-Swim Operators in the Modified Bacterial Foraging Algorithm for the Optimal Synthesis of Four-Bar Mechanisms

Table 8

Statistical results obtained in 30 independent runs by TS-MBFOA and the DE-based approach when solving the three four-bar synthesis problems. Best results are remarked in boldface. No significant differences were found based on the 95%-confidence Wilcoxon test.
